Answer:
7 protons, 7 neutrons (READ EXPLANATION)
Explanation:
The atomic number represents how many protons are in an element. Generally speaking, elements have the same number of protons and neutrons. So, an element with the atomic number of 7 will have 7 protons and 7 neutrons.
However it is possible for an element to have a differing number of neutrons (an element will always have the same number of protons because that number is how the element is identified in the first place). Elements that have a number of neutrons that is not the same as the atomic number are called isotopes.
